Field Experiments

Question 1

Features

Answer 1

• Field experiments are conducted in a more natural enviorment
• Deliberate changes to IV
• Measures the DV (usually quantitative data
• Experimenter controls some of the extraneous varibles

Question 2

Strengths

Answer 2

• Greater ecological validity. This makes it so the situation is more likely to happen in day-to-day life, being more realistic. This means it can be applied beyond the experiment.
• Less bias from demand characteristics. if it’s in a real life situation the pt’s feel like they’re in everyday normality. This means that they won’t cause many pt’s extreaneous varibles.

Question 3

Weaknesses

Answer 3

• More difficult to establish cause and effect. The experimenter is in another setting and they can’t control the siutation as well as a lab experiment. This means that it is harder to establish cause and effect which may question the results
• more difficult to check reliability because it hasn’t been controlled and is less of a standardised procedure, this means it is harder to replicate.
